            Bug ID: 50739
           Summary: Race condition in regression test bug49334.cpp
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Runtime Library
          Assignee: unassignedbugs at nondot.org
          Reporter: llvm at meinersbur.de
                CC: llvm-bugs at lists.llvm.org, tianshilei1992 at gmail.com

The regression test bug49334.cpp occasionally fails because of a race condition
in the asynchronous data movement. The test case was introduced in
https://reviews.llvm.org/D97329 to fix http://llvm.org/PR49334. PR49334 was a
null dereference not a race condition.
